Abstract
An illustrative example method of positioning an elevator door interlock includes positioning an elevator car in a hoistway near the hoistway door so that at an elevator door coupler is aligned with the interlock, opening a door of the elevator car and the hoistway door, accessing an adjustment mechanism supporting the interlock from outside of the hoistway, and using the adjustment mechanism to adjust a position of the interlock relative to the hoistway door from outside the hoistway.
Claims10
A method of positioning an elevator door interlock associated with a hoistway door that selectively closes off an opening into a hoistway, the method comprising:
- positioning an elevator car in the hoistway near the hoistway door so that an elevator door coupler is aligned with the interlock;
- opening a door of the elevator car and the hoistway door;
- accessing an adjustment mechanism supporting the interlock from outside of the hoistway;
- and
- using the adjustment mechanism to adjust a position of the interlock relative to the hoistway door from outside the hoistway.
An elevator door assembly, comprising:
- a hoistway door that is moveable between an open and a closed position, the hoistway door including a vertically oriented edge that is visible when the hoistway door is in the open position;
- an interlock including
- a latch that is moveable between a door locking position and a released position,
- a lock that cooperates with the latch to lock the hoistway door when the latch is in the locking position, and
- at least one bumper configured to be contacted by a vane of an elevator door coupler at least for moving the latch into the released position;
- and
- an adjustment mechanism that is accessible along the vertically oriented edge of the hoistway door when the hoistway door is in the open position, the adjustment mechanism selectively moves the interlock to adjust a position of the at least one bumper relative to the hoistway door.
